The application field of pvd coating machine is very wide. It can be said that it involves all walks of life. The major fields can be divided into decoration, optics, auto parts, hard coatings, semiconductors, etc., then the categories can also be divided according to materials, such as decorative plastic products, So what is the application of vacuum coating machine in plastic products? After the surface of plastic products is metallized, the application range of vacuum coating machine in plastic products will be wider. The vacuum coating on the surface of plastic parts can be divided into functional coating and decorative coating.

       As a functional coating, it can improve the physical and chemical properties of the surface of plastic parts, such as improving the dimensional stability and electrical conductivity of plastic parts;
       As a decorative coating, the surface of the plastic parts can have metallic luster and can be produced in different colors according to the actual decoration requirements, such as golden yellow, bronze, metallic red, metallic green, metallic blue, etc.
       pvd coating machines are widely used in plastic products. Plastics have the characteristics of easy molding, low cost, light weight, and no corrosion. Plastic products are widely used, but their shortcomings restrict the expansion of applications, such as unsightly, easy aging, mechanical Poor performance, poor heat resistance, high water absorption. Through the application of vacuum coating technology, the plastic surface is metallized, and the organic and inorganic materials are combined, which greatly improves its physical and chemical properties. Its advantages are mainly reflected in:
       1. Easy to clean, no vacuuming.
       2. Make the plastic surface conductive;
       3. Improve the appearance, the surface is smooth, the metallic luster is colored, and the decoration is greatly improved;
       4. Reduce the water absorption rate, the more times of coating, the fewer pinholes, the lower the water absorption rate, the product is not easily deformed, and the heat resistance is improved;
       5. Improve surface hardness: The original plastic surface is softer than metal and easily damaged. Through pvd coating, the hardness and wear resistance are greatly increased;
       6. Improve weather resistance. Usually plastics age very quickly outdoors. The main reason is ultraviolet radiation. After aluminum plating, aluminum has the strongest reflection of ultraviolet rays, so the weather resistance is greatly improved.
